Abstract: PURPOSE:To enable easy switching between recording of characters and recording of non-character images through using a single thermal head, by providing a common electrode with a changeover switch for grounding, and providing some or all of a plurality of recording electrodes with switching means for grounding in a predetermined order. CONSTITUTION:In the case of recording characters, a changeover switch 6 is turned ON to ground a common electrode 2, changeover switches 41, 43 and 44 are used under ON/OFF control according to a recording control signal, and changeover switches 42 and 45 are used between a contact (a) and a contact (c) under on an ON/OFF bias according to the recording control signal. In this case, every one of recording electrodes 31-35 functions as a recording element, so that ink picture element regions become as indicated by broken lines 61-65. In the case of recording halftone dot images, the changeover switch 6 is turned ON and OFF, and the changeover switches 42 and 45 are set to a contact (b), thereby grounding the recording electrodes 32 and 35. In addition, the changeover switch 43 is left OFF so that the recording electrode 33 does not function to record. When the switch 41 is turned ON, an electric current flows between the adjacent electrodes 31 and 32, resulting in that a broad region corresponding to two picture elements as indicated by a broken line 66 is heated.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device with high reliability, and to provide a semiconductor device which can prevent latch up, ensure a specified dielectric breakdown voltage and is not easily broken when treated in an assembly operation or the like. SOLUTION: An NPN transistor part 42 and a PNP transistor part 44 are formed on a wafer substrate 32. Since the wafer substrate 32 is a highquality single crystal cut from an ingot, reduction in reliability due to crystal defects or the like can be prevented by forming transistor parts on the wafer substrate 32. The density of impurity in a first base layer 38 is set low to ensure a specified dielectric breakdown voltage between a buried diffusion layer 34 and a second base layer 40. The density of impurity in the second base layer 40 is set high to reduce resistance components while ensuring the thickness. In this way, latch up can be prevented while maintaining the strength.

CONSTITUTION:In regulating a head gap, when the leading end of an L-shaped operation lever 20 is detached from either one of engaging holes and revolved, eccentric bearings 19A, 19B and a guide shaft 3 also revolve but, since the center axis Q of the guide shaft 3 is upwardly shifted from the center axis P of the eccentric bearings 19A, 19B, the guide shaft 3 performs circular arc motion forwardly and backwardly around the center axis P of the eccentric bearings 19A, 19B and a carriage 2 also performs forward and backward movement by the forward and backward movement of the guide shaft 3 to regulate the head gap. The forward and backward movement of the guide shaft 3 simultaneously becomes that of the rack gear 9 united with arms 9A, 9B. Since the rack gear 9 also moves forwardly and backwardly in connection with the regulation of the head gap due to the forward and backward movement of the carriage, the distance between a drive gear 10 and the rack gear 9 does not change and the meshing of both gears is kept constant and the stable feed of an ink ribbon becomes possible.
